Mechanisms for cloud-based configuration and management of network devices using network mediators implemented in the network devices

Abstract

An improved method for configuring and managing network devices using network mediators is provided. The improved method comprises receiving, at a network mediator executing on a network device, from a device management server, one or more policies for configuring or managing the network device. For each policy from the one or more policies: the network mediator determines, based on the policy, one or more instructions for configuring or managing the network device, and transmits the instructions to the network device. Upon receiving, from the network device, a response to the instructions, the network mediator determines whether the response satisfies one or more conditions set forth in the policy. In response to determining that the response satisfies the conditions set forth in the policy, the network mediator generates a message based on the response, and transmits the message to the device management server.
